The **FF20-23A-R11A** is a specific electronic connector manufactured by **DDK (Dai-Ichi Denshi Kogyo)**. It belongs to the FF20 series, which consists of high-density, low-profile **Flexible Printed Circuit (FPC)** connectors. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Connector Type** | FPC (Flexible Printed Circuit) Connector | | **Number of Contacts** | 23 Pins | | **Pitch (Spacing)** | 0.5 mm | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Actuator Type** | Flip-lock (ZIF - Zero Insertion Force) | | **Contact Position** | Bottom Contact | | **Current Rating** | 0.5A AC/DC | | **Voltage Rating** | 50V AC/DC | --- ### 2. Physical Design and Functionality * **Zero Insertion Force (ZIF):** The "R" in the part number often signifies a rotating or flip-lock actuator. This allows the FPC cable to be inserted with zero friction, and then locked into place by flipping a lever, ensuring a secure electrical connection. * **Low Profile:** These connectors are designed for modern, slim electronics where vertical space is limited. * **Bottom Contact:** This indicates that the conductive traces on the flexible cable must face **downward** toward the PCB to make contact with the internal pins. --- ### 3. Materials and Durability * **Housing:** High-temperature thermoplastic (usually LCP), suitable for lead-free reflow soldering. * **Contacts:** Copper alloy with gold plating to prevent oxidation and ensure high conductivity over time. * **Operating Temperature:** Typically rated from **-40°C to +85°C**, making it suitable for both consumer and industrial applications. --- ### 4. Common Applications Due to its small 0.5mm pitch and high pin count (23), the FF20-23A-R11A is frequently found in: * **Mobile Devices:** Connecting LCD screens or touch panels to the mainboard. * **Cameras:** Internal wiring for image sensors and control buttons. * **Laptops/Tablets:** Linking keyboards, trackpads, or small peripheral boards. * **Medical Equipment:** Compact handheld diagnostic tools.
